HAY-PRESS.

SEECIFICATION forming part of Letters Patent No. 746,073, dated'Decmber 8, 1908.

Application fil ed February 4, 1903. Serial No. 141,926. (Nomodeld To all whom it may concern: Be "it known that I, J OEL B. HALL, a citizen of the United States, and a resident of Harriman, in the county of Roane and State of Tennessee, have invented certain new and useful Improvements in Hay- Presses, of which the following is a specification.

The object of my invention is to produce a simple but effective press of this character wherein all possible lost. motion is taken up and the full force andefliect f the power ex erted; and with this and minor objects in View my invention consists of the parts and combination of parts, as will be hereinafter more fully set out. In the drawings, Figure 1 is a side elevatio of the press embodying my invention. Fig.

2 is a top plan of the'same. v

1 represents the main sides of the frame, set upon subsills 2. The forward portion of the frame is provided with any approved type of baling-box having the usual braces 4.

5 is the opening through which the hay is supplied to the press.

6 represents bars carrying the usual balingdogs on the inside of the press, said dogs not being shown. Said bars are mounted upon rods 7, provided with cap-nuts 8, between which and said bars is interposed the coilspring 9, whereby said rods and the dogs carried thereby are given a resilient mounting.

10 represents cross-timbers extending from the side timbers 1 and connecting said side timbers. i v

11 represents torsional braces, theends of which are anchored to the cross-timbers 10.

12 is a loop, the free ends of which are secured to the forward'ends of the torsional braces 11..

13 is a brace, the ends of which are secured to the side of the 'baling-chamber, while its middle portion is extended inthe form of a loop toward the torsional braces 11. the loop frame, upon which is secured a double cam 16, the straight faces of which, while on opposite sides of the axis of the cam, are par.-

allel with each other. Above the cam on the shaft 15 is mounted a ratchet-wheel 17, above which, on the same shaft, isloosely mounted a sweep 18, said sweep being provided with a spring-dog 19, adapted to engage the ratchetwheel-17. p

20 is the lead-bar, secured to; the sweep.

21 is a plunger to which a pitman 22 is suitably pivoted, the :rearend of the pitman being deflected to one side, as at 23, at its extreme rear end, and provided with an antifrictionroller 24, constructed for engagement with the cam 16. Said pitman is provided with a guard 25, the object of which is to prevent the roller 24 from becoming locked in the lowermost point of the cam.

26 is a link pivoted to the-corner of the frame diametrically opposite the corner to which the cam 16 is secured, the forward end of said link being pivoted to the free end of the pitman-rod 22, as more clearly shown in Fig. 2, thereby forming in connection with red 22 a toggle-lever, which folds or closes in a direction toward the axis of the cam 16.

27 is a coil-spring, one end of which is secured to the side of the frame opposite that to which the link 26 is pivoted, while the other end is secured, by means'of a bolt 28,

begins to ascend the short curved face of the cam, whereupon power is exerted directly upon the rod 22; but as soon as the antifriction-roller is in engagement with the long curved face of the cam the link 26'is brought into play, thereby bringing into I effect the forces of the toggle-lever, and this togglelever is of such construction that it may be extended its full length-that is to say, it may be brought for all practical purposes to a dead-center, whereby all of the effective power of such a lever is exerted upon the plunger in the baling-box. As soonasthe antifri'ction:

roller 24 is about to leave the long curved face of the cam 16 the coil-spring 27 immediately retracts the plunger and by reason of its Power being applied to the sweep 18, the antifriction-roller position with reference to the link 26 folds or retracts the toggle-lever until the antifriction-roller is at the lowest point on one of the straight faces of the cam, the guard 25 preventing the antifriction-roller from being locked between the straight and the short curved faces of the cam.

It will be readily seen by those skilled in the art that by reason of the relative positions of the cam, the link 26, and the spring 27 I am enabled to secure the full force and effect of these several elements. I

Having thus described my invention, the following is what I claim as new therein and desire to secure by Letters Patent:

1. In a hay-press, the combination with the baling-box,a brace secured on each side thereof and extending beyond the boX, crossed braces secured to the frame of the press at one end, a substantially V-shaped brace connecting one end of each of said crossed braces and adjustable means connecting said V-shaped brace with the brace secured to the balingbox, of a plunger, a link pivoted at one end to one of said crossed braces and at its other end to the plunger, a cam pivoted to one end of the other crossed brace and a spring connecting the plunger and frame of the press.

2. In a hay-press, the combination with a double cam secured to one side of the frame, a sweep to operate said cam and slip-joint between said cam and its sweep, of a link pivoted to the side of the frame opposite to that to which the cam is pivoted, a plunger one end of which is deflected and provided With an antifriction-roller for engagement with said cam, said plunger being pivotally secured to said link and a coiled spring, one end of which is secured to the plunger, while the other end is secured to the side of the frame opposite that to which the link is pivoted, and a guard secured to one side of the plunger near its deflected end.

The foregoing specification signed this 5th day of January, 1003.
